I told you already, feature-wise, there is more than enough there. :) Perhaps the shortcuts I've already mentioned in my comment on the product page. However, they're not essential at all.

The only annoyance I've found is that once in a while I can't put down a color which is already present in a certain character (no matter if it's a background or ink color). It's rarely happening and no idea why but a save/reload solves the thing.

And thank you once again for this lovely tool which made my life much easier when my C64 was broken, and it also comes very handy here at work when I'm bored! ;)

edit: that depends on where on the screen is the winodw placed. In some areas of the screen there is some flickering, while in others there is none, while in others you can see only one field (half of the picture).
